 // Description:

 // e32test\math\t_r32.cpp

 // T_R32.CPP - Test routines for TReal32

 // Also note that these tests do not generally include testing of special values.  This is done

 // in T_R96 tests and conversions are tested thoroughly, so explicit tests are unnecessary here.

 // Overview:

 // Test functionality of operations on 32bit real numbers.

 // API Information:

 // TReal32. 

 // Details:

 // - Test the conversion from TReal to TReal32 is as expected.

 // - Check addition, subtraction and multiplication of 32-bit floating point

 // numbers are as expected.

 // - Check division of 32-bit floating-point numbers and verify that it is

 // panicked when divided by zero.

 // - Test arithmetic exceptions are raised for

 // - overflow error during addition, subtraction.

 // - overflow, underflow errors during multiplication.

 // - overflow, underflow, divided by zero errors during division.

 // - overflow, underflow, invalid operation errors during conversion

 // from double to float.

 // - Check unary operator, equalities and inequalities operators, pre/post 

 // increment, decrement operators with TReal32 are as expected.

 // Platforms/Drives/Compatibility:

 // All 

 // Assumptions/Requirement/Pre-requisites:

 // Failures and causes:

 // Base Port information:
